Let's divide 325400 by 78
The aim is to understand the frequency of 78 in 325400.

Step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 78

Advancing to step 2:
78 can be fit into 32 0 times, resulting in a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 78

On to step 3:
If we divide 325 by 78, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 312 from 325 and we're left with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 78

Advancing to step 4:
134 divided by 78 is 1 with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 78 from 134 to get 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 78

Let's proceed to step 5:
78 can be fit into 560 7 times, resulting in a remainder of 14.
The next digit of our result is 7. 
Result so far: 417.0
If we subtract 546 from 560, we get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 78

Let's proceed to step 6:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 4171.0
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 4171.7
The remainder is 74 after subtracting 546 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
740 divided by 78 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 4171.79
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
When dividing 380 by 78, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 4171.794
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
When dividing 680 by 78, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 4171.7948
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
If we divide 560 by 78, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 4171.79487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 4171.794871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 4171.7948717
The remainder is 74 after subtracting 546 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
740 divided by 78 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 4171.79487179
Subtracting 702 from 740 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 4171.79487179, with a leftover of 3.8e-08.
